SPECIFICATION forming part of Letters Patent No. 350,603, dated October 12, 1886.

Application filed December 16, 1885. Serial No. 185,815. (No model.) Patented in England July 1, 1885, 1T0. 8,001.

of America, and a resident of London, England,

have invented new and useful Improvements in the Manufacture of Horseshoes and in Machinery or Apparatus therefor, (for which I.

have obtained provisional protection in Great Britain, No. 8,001, hearing date .Tulyl, 1885,) of which the following is a specification, reference being had to the accompanying drawm s.

IlIy invention relates to the manufacture of horseshoes and to machinery or apparatus therefor, and comprises various improvements hereinafter described.

In the specification of former Letters Patent, dated October 10, 1882, No. 265,705, the manufacture of spring-horseshoes by means of spe cially-designed machinery or apparatus is described. This apparatus comprises a pair of curved dies for drawing the blanks and forming the calks thereon, and another pair of dies for finishing the blanks; but by these dies only one-half of the blank is operated upon at a time-that is to say, after one half of they blank has been shaped or finished by either pair of the said dies, the blank must be reheated and the other half thereof inserted between the dies, in order that the two halves of the blank shall be shaped as required for the two sides of the shoe.

One object of my present invention is to provide for the manufacture of horseshoes by one operation of each pair of dies employed.

In the accompanying drawings, Figure 1 is a plan view of a bending-machine, showing the parts in the positions which they occupy when the machine is ready for starting. Fig. 2 is a plan view of the same with the parts in different positions. Fig. 3 is a vertical longitudinal central section showing the parts in the position which they occupy when the operation of bending the blank is completed. Fig. 4 is an enlarged transverse sectional view on the line at w of Fig. 2. Figs. 5, 6, 7, and 8 are details to be referred to.

In Figs. 1, 2, 3, and 4, d is the base-plate of the machine. e is a former, which is designed tooperate in combination with dies, hereinafter described, to bend the blanks to the desired shape, and which is firmly attached, by bolts 6' or otherwise, to the flattened end of a bar or rod, 6 This bar is secured, by bolts or otherwise, to a block, 6 fitted to slide to and fro between guides d d fixed or formed on the base-plate d. The said block is coupled by means of a connecting-rod, f, to the pin 9 of a disk-crank, g, which is fixed upon ashaft, h, carried in .bearings h, and which acts as a fly-wheel. Atoothed wheel, 12?, is mounted loosely upon the shaft h, and is adapted to be connected therewith or disconnected therefrom by means of a clutch, k operated by a foot-lever or treadle, 2', through the medium of the levers 2" j is a pinion, which is fixed on a shaft, j, carried in bearings j", and which is geared with the wheel h I 4 j is a driving-pulley fixed on the shaft j, which pulley is to be connected bya belt with any suitable motor. By these means reciproeating motion is imparted to the former e, for

the purpose hereinafter specified.

I; la are dies whose inner edges have the shape or configuration which it is desired to give to the shoe. These dies are firmly se cured,by bolts or otherwise, to blocks or holders k pivoted at is to a plate, Z, resting upon the base-plate d, so that it is free to slide thereon.

10* is a tie-bar connecting the pivots of the holders k".

m m are two links, which fit into vertical grooves or recesses in the holders 7c and in blocks n, so that they will act like a togglejoint. The blocks n have screw-threaded extensions n, which are passed through lugs or brackets d formed on or secured to the baseplate d, and are provided with nuts n Washers or distance pieces'n are placed upon the extensions a between the blocks n and the lugs (1 By slackening the nuts 11?, removing the washers a and inserting washers of greater or less thickness in place thereof, the dies k k and holders k can be adjusted to suit different sizes of shoes. The links m m are coupled to the holders k and blocksnby bars or links 121..

o o are adjustable blocks provided with antifriction rollers 0, and so arranged that the former e'in its to-and-fro movement will pass between them. threaded extensions 0, which are passed These blocks have .screw- ICC through lugs or bracket-s d, formed on or secured to the base-plate d, and are provided with nuts 0. \Vashers or distance-pieces 0 are placed upon the extensions 0", which washers can be replaced by thinner or thicker washers, as above described with reference to the blocks a. The said blocks 0 are formed with slots 0 and are secured to the base-plate d by bolts 0, passing through the said slots.

19 p are springs attached to the blocks 0, for the purposes hereinafter specified.

l is a weight attached to one end of a rope or chain, 1', which passes around a pulley, 1 carried by a bracket, d formed on the base plated. The other end of the said rope or chain is attached to a rod, 1*, passing through a guide-block, d9, secured to the said baseplate. This rod is attached, by a bolt, Z", or otherwise, to the plate I.

The operation of the machine is as follows that is to say: In Fig. 3 the parts are, as above stated, shown in the positions which they occupy when the machine is ready for starting. The blank B is placed endwise between the springs p, as shown, which springs hold the said blank until the former 6 acts thereon, as hereinafter described. The said springs permit of readily ascertaining whether the blanks are of the proper length to form a shoe of the desired size, because if a blank is too long it cannot be inserted between the said springs, while if a blank is too short it will not touch the two springs. After a blank of the proper length has been heated and inserted between the said springs, as shown, the treadle z is depressed to start the machine. The rotation of the disk-crank g first causes the former e to move forward or toward the dies ink. In this forward movement a pointed stud or projection, e*, on the former e first enters the blank at the center thereof, and thus prevents its displacement while being bent. Thesaid former then forces the blank betweenthe rollers 0, and thereby bends the said blank. It then thrusts the said blank between the dies k k, thereby moving the said dies and the plate Z forward, this movement being assisted by the weight Z. The dies 7c in their forward move ment are turned around or about their pivots by the links 171. m, and the blank is thus forcibly pressed between the dies 70 k and the former e, to impart to it the required shape. The parts then occupy the positions indicated in Fig. 2, in which S indicates the shoe. While the blank is being bent the flattened head of the bar 6* holds down the shoe and prevents the twisting or distortion thereof. The continued rotation of the wheel g causes the backward or return movement of the former e. In the first part of this backward movement the plate 1 and dies It It move back with the former 6, so that the said dies are opened by the links at m. In the continued backward movement of the former ethe shoe is withdrawn thereby v from the dies 70 7c and moved back with the said former until it arrives over the aperture d in the baseplate' (Z, th rough which aperture it will fall upon the ground or into a suitable receptacle.

The former c and forming-dies 7c is are removable from the rod 0 and the holders 7c, and can be replaced by other formers and dies. Therefore the machine can be adapted for manufacturing horscshoes differing in size or in shape, or in both size and shape. The manner in which the dies 70 k are secured to their holders is more clearly shown in Fig. 5.

In Figs. 6 to 8, inclusive, I have shown a pair of drop-dies, A B, the lower one, A, of which is made with a groove or channel, A, and the upper one, B, of which is made with a projection, B, which will fit into the groove or channel A. The said projection, however, leaves a space at the inner end of the groove or channel A, so that when a shoe is compressed between the said dies the metal will be forced into the said space, and a toe'clip will thus be formed on the shoe.

I provide the means, hereinafter described, whereby the shoe can be readily removed from the lower die after it has been operated upon therein-that is to say, a forked lever, G, is pivoted at O to the lower die, A, and is coupled to two rods, D, which extend through holes in the said die, so that they will bear against the under side of a shoe therein. This lever is arranged tobe operated either by hand or by the foot, or automatically by the same means whereby the upper die is raised, or by any other suitable means.

I do not claim in this application the rolls between which the billet is passed to form the blanks, nor do I claim the cutters herein shown and described, as these features are designed to form the subject-matter of application to be filed hereafter.

\Vhat I claim is-- 1. The combination, with the base-plate having lugs or brackets dflof the former e and mechanism for imparting reciprocating motion thereto, he adjustable blocks 0, having threaded extensions, the rollers mounted in said blocks, the adjusting washers on the threaded extensions, and the pivoted dies 7th, substantially as herein described.
